Dr. Lung-Chang Chien (Epidemiology and Biostatistics) recently co-authored and published a research article, "" in Industrial Health. Findings reveal that workers on weekly rotations involving 3–5 consecutive nights had 5%–10% significantly higher cardiovascular disease risk estimates than workers on the permanent day shift. Workers on weekly rotations also had 6%–8% higher BMI-based CVD risk estimates than those on the monthly rotation involving two consecutive nights. In conclusion, the length of the shift cycle and the number of consecutive night shifts should be considered in interventions for the prevention of cardiovascular diseases.
